HAIR/IE-FASTENER.

To all whoa nit may concern:

Be it known that 'I, LAURIEN acitizen ofthe BLUn'r,

of Cook and State of Illinois, have inventednew and useful Improve'mentsin flame-Fasteners,- of which the following is afull, clear, concise, and exact description,- referenoe being had tothe accompanying drawings, forming apart of this specification.

My invention relates to improvements inhame fasteners, and has for its ob ect the ,which can be easily stamped or pressed from r chain locking member;

metal and readily attached and detached from the hame.

A further object is the production of a device the various parts of which are so constructed and assembled as most impossible for the device tached when-in use.

A further object is the production of improved means for locking the fastener inany to become dedesired position.

'A further object is the production of a device that canbe cheaply manufacturedand is not, liable to disarrangement.

{These and. such other objectsas may herer :inafter appear are attained; by my device,

embodimentof which is illustrated in the accompanying drawing, in which- 7 1 Figure 1 represents a view of my im; proved device locked in position and with a member ofthe device in unlocked position shown in dotted-lines.

Fig. 2 represents i-a view of the device shown in- Fig. 1.

outer link: comprising. a; straight wire ormetal bentinto a loop with lateral-1y. extending ends 30'30 forming a bar, provided with clown-turned ends 30 The. propiece pf,

vision of these down-turned ends prevents I the bar from slipping through the locking washer hereinafter described as, if the chain is suddenly pulled through, the shoulders or up-turned portions of the safety stop, bar

prevent the bar from passing through.

In order to form a stop and lock for the device when in position, I provide a looking Washer. 31 formed from a circular piece of metal ed ear 33 having an opening 35 preferably quadrangular, through which a locking pin the-opening'35 when the washer is flat, but;

v Wardly andupwardlyr In the first quarter of the revolution the pin 17 bears against the upperedge of the groove- 16, but as t'helever' passes vertically and commences' to swing upwardly, the pin 1-7 slides down in r the groove until it reaches the bottom 1 as shown 3 in full lines-in Fig."1,"th hook -1-5 being passed up over the outer surface-of the hook when the ear 33 is bent upwardly-at right angles to the body as shown at 40in F ig.;1,;

the length of the opening 35 is reduced by the bending, so that the remaining opening *is such that the pinmember passes back and forth, but "cannot pass outside of the washer by reason of-the engagement of the hook member against the abutting face of the upturned ear on one side and the en'- larged ring portion at the otherzend abub' ting'the opposite face of the earl-;

Referring now to the operation of m device, the hook 11 is put over the link l2ton the hame 13, with the leverand chain hang-x ing. The chain B is detached from the loc ing washer and passed through the link ll on the bottom .of the opposite hame-42. The

locking'washer F is then slippedover the bar and the chain pulled up fairly tight, the washer F being the outerface of the 40 uppermost.

pulled by hand and the locking washerseej curedin place, the locking lever=isswung upwardly onthe pivot 17 and the pivot slides 't'o 'the top'of the slot 16. The locking lever is then grasped in the hand" and swungoutitightly together. i

' the entire mechanism is securelylocked in with an opening '32 and an extend-i.

loosely pressed snugly against The only way that the device can be un- 1 locked; is to pressdownon the top of, the

.which moment the pull throws the hook back and loosens the device, the pin 17 rising to the upper end of the slot 16. I V

.In this device I have corrected a great many faults present in most other fasteners now on the market,;and have made one that is practically fool-proof, with nopart-s to get outfof order. and loose, and constructed in a-strong and durable manner, and one that is perfectly adjustable, fitting all sorts and sizeof' hames now in use. While I have shown a specific construction, there arenumerous modifications that would occur'to' those skilled in; the art which would come within the spirit of my'invention; 1

Having thus described my invention, what I claim as newand desire to-securebyLetters Patent is: a
